FIRE-PROOF ROOF, FLOOR, 86C.

SPECIFICATION forming part of Letters Patent No. 349,670, datedSeptember 21, 1886.

Serial No. 179,354. (No model.)

To all whom it may concern:

Be it known that I, J. FRANKLIN STUOKERT, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful 1mprovement in Fire-ProofRoofs, Floors, Ceilings, &c., which improvement is fully set forth inthe following specification and accompanying drawings, in which Figurelrepresents a transverse vertical sec tion of abuilding to which myinvention is applied. Figs. 2, 8, 4, and 5 represent portions of thesame on enlarged scales.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of means for proteeting roofs, floors, ceilings,walls, &c., from fire,

set forth.

Referring to the drawings, A rep resents a floor, andB a ceiling. Belowthe ceiling are convex or arched gutters 0, consisting of plates ofcorrugated metal or other suitable material, secured to the beams orgirders D in any suitable manner, forming channels or passages, intowhich water, steam, acid, or other cooling or fire-extinguishing mediumisintroduced from pipes E, which are connected with a pipe, F, thelatterbeing in communication with a pipe, F, or system of pipes, main G, orother source of supply, or a branch, H, to which a fire-engine or pumpmay'be attached. As shown in the drawings, the pipe E opens into thegutter 0 at the highest part thereof, so as to direct the stream to bothsides of the curve. The beams or girdersare made either hollow or havetubes or sections of tubes connected with them, which form receptaclesfor water, said receptacles being in communication with the pipe F. Thecolumn J is made hollow and connected with the pipe F by a suitablebranch, J, so as to be in eommmiication with the main G or place ofsupply, and be filled with water or other fluid, whereby it is protectedfrom heat. Said column may have perforations, so as to permit the fluidto escape therefrom and enter the apartment where the fire exists.-

K represents the door of an apartment, an elevator, &c., thelsame beingmade hollow, and being in communication with the pipe F by a suitablepipe, F there being an opening in both the top casing and the top of thehollow door, so that the door may when closed be filled with fluid andreadily opened and closed. The gutters 0 not only direct the wateragainst the metal bearings to protect them from heat, but also serve tocatch any leak from the floor or roof above.

\Vhere the beams, girders, or metal joists and gutters are combined, orthe gutters divided by a web, small openings may be made whereverdesired, to admit of the water or fluid circulating in any desireddirection. In cases where the hollow girders or columns are large, thesame may be partly filled by a hollow or solid body or core, so as todecrease the fluid-space of said girders or columns.

To the beams or girders maybe secured gutters L, which are so disposedat the ends of the gutters O as to receive the Water or fluid admittedtherein, orleak or moisture from the floor or root, shown'in Fig. 3 andin the right hand of Fig. 2 and left-hand part'of Fig. 4-. Vhen thepressure of fluid admitted to the gutters C is sufficient, the fluidwill overflow at the gutters L and so be directed into the apartment,serving to extinguish fire therein.

In place of the pipes E communicating withthe gutters 0, short pipes E,(see Fig. 1,)leading from the pipe F and opening into the apartment,|maybe employed. It may also be well to useboth the pipes E and E. Acheck-valve, M, is connected with the pipe F, to prevent the return ofwater to the main whenatank is employed for supply of water.Acheck-valve, N, is connected with the pipes E, for the purpose ofdistributing the water either to the gutters O or other parts of thebuilding, as desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The ceiling B, in combination with thecurved gutter O and girders DD, the said gutter having an inlet-pipe, E, opening into the same at itshighest part, substantially as and for the purpose set forth.

2. The floor A, in combination with the ceiling B and gutter G, thelatter extending under the surface of thesaid ceiling, and forming asingle chamber between each adjacent pair of girders, substantially asdescribed.

3. A ceiling and a gutter below the same, in

combination with the pipe E, which is in communication with said gutter,substantially as and for the purpose set forth.

4. A hollow beam or girder provided with the gutter L, substantially asand for the purpose set forth.

5. A ceiling with a gutter below the same, in combination with a troughor gutter attached to the supporting-beam, substantially as (le- 1oscribed.

6. A ceiling and a gutter beneath the same,
